The Mets misused Mejia under Jerry Manuel, bouncing him from the bullpen to the rotation. There was undue stress and a resultant injury that lead to Tommy John surgery.

MEJIA: Gets another chance. (AP)

Last season was a waste, but Mejia will be recalled to start one of the double-header games Friday in Washington instead of pushing Wheeler back a day.

Wheeler has been suffering with blisters, but Terry Collins said they’ve healed and the rookie had his regular throw day Tuesday.

Mejia started for Double-A Binghamton Saturday and gave up one run on three hits and two walks with eight strikeouts in six innings.

Mejia’s stock has fallen severely, but if he does well and sticks, he could address two situations: If they continue to use him as a starter it might enable them to rest Jon Niese longer. If their ultimate plan is as a reliever, then he should report to camp in that role.

DUDA, d’ARNAUD UPDATES: Left fielder Lucas Duda, on the disabled list with a left intercostal strain) in on a rehab assignment for the GCL Mets. He’s still several weeks away, but when he returns he shouldn’t immediately get his left field job returned to him.

Although Eric Young has cooled, he’s still productive at times and has been instrumental in the Mets turning around their season. Also, Young has finally given the Mets a presence at the top of the order.

Regarding Travis d’Arnaud, the plan was for John Buck to keep his seat warm until he was ready to play. A fractured foot quashed that scenario and d’Arnaud might be a September call-up at best. He has just started playing rehab games.

MARCUM RELEASED:Shaun Marcum reported to training camp out of shape and was quickly injured. He left the Mets the same way and was given his unconditional release.

After several long and solid relief appearances, it was thought Marcum might get something in a trade, but Niese’s shoulder injury forced the Mets to keep him on the roster.

Had Marcum stayed, his only value to the Mets would have been to the media for Ryan Braun quotes.

METS MUSINGS: It remains to be seen if Jordany Valdespin’s temper tantrum after his demotion will force the Mets to dump him. However, Valdespin somehow fell into luck in Las Vegas as he’s gotten a chance to play with Wilmer Flores on the minor league DL with an ankle injury. I thought Valdespin was done, but he’s 10-for-25 with two homers and 13 RBI for Vegas. If he keeps that up, we’ll see him in September. … Minor league catcher Alex Machillanda is the clear-cut winner of the Idiot of the Month Award after he was busted for shoplifting in Port St. Lucie. Minor leaguers don’t get a lot of money, but there’s no justifying stealing.
